The traditional 3-layer feed forward BP network modal of morphological opening and closing operation was modified by extending the input layer data.

采用扩展输入层数据的办法修正了传统的形态开、闭运算三层前馈BP网络模型。

Morphological opening-closing is implemented using vertex-collapse algorithm. A nonlinear scale space will be constructed efficiently with perfect shape preserving.

然后采用顶点塌缩算法实现的彩色形态学开闭算子生成了所需的非线性尺度空间；
